CINDERELLA: Progressing paludicultures after

centuries of peatland destruction and neglect

In living peatlands: • Production is larger than decay • Dead plants accumulate as peat

Kolkheti, Georgia

Peat accumulates through water saturation: Natural peatlands are wetlands!

Scotland

Lesotho

Peat accumulates during thousands of years and stores concentrated carbon in thick layers

Peat of 2 m deep

Very important but not appreciated: the Cinderella Syndrom

Ruoergai, China

Peatlands are the most effective carbon stores of all terrestrial ecosystems

Kyrgystan

While covering only 3% of the World’s land area, peatlands contain 500 Gt of carbon in their peat.

Germany

Germany

i.e. twice the carbon stock of the world’s total forest biomass

Problem: Our arable farming had a semi desert as a cradle…

…and has since the idea that productive land must be dry…

Qatar

…and soils continuously be moved…

Qatar

…illusions that we worldwide apply to wet, organic soils…

Greta Gaudig Germany

… with African desert plants on drained peat: Aloe vera…

Bostang Radjagukguk Kalimantan

… or semi-arid Maize on drained peat…

Palm oil can grow and produce well on peat … or with oil palm on drained peat…

Marcel Silvius Malaysia

…peatland use with problems that we start to see only now...

Sabine Wichmann Germany

…that often does not even allow harvest…

Jilin, China

… a land use that has desertified millions of hectares…

Ukraine

…and in continental areas creates soils like made of stone…

Ukraine

Mobilisation of the carbon stock by peatland agriculture and forestry leads to huge emisisons

Norway

Clear relation between mean water level and annual emissions (CO2, CH4 and N2O)

Deeply drained grassland on peat in Germany emits 29 T CO2-eq ha-1a-1 = 145.000 km with middle class car

A potato field on peat in Germany emits 37 T CO2-eq ha-1a-1 = 185.000 km: every hectare, every year

Bavaria, Germany

Potatoes from peat are fossil resources…

Forests on drained peat generally loose more peat carbon than the trees sequester…

Jilin, China

Wood from peat is fossil …

Agricultural peatlands in Germany emit almost twice as much CO2 as Jähnswalde, the World’s 7th most dirty power station

Jähnswalde

Globally, degraded peatlands emit 2 Gigatonnes CO2 a-1

CO2 emission

Drained peatlands on 0.3% of the land emit 5% of all anthropogenic CO2

Indonesia leads the list of global top emitters…

The EU is a good second…

Denmark

In Germany peatland agriculture causes annually a climate damage of € 3 billion, and gets 300 million EU-grants (CC)

Sabine Wichmann

Per joule energy „biogas“ from mays from peat causes 8x more climate damage than burning lignite…

… and that with subventions under Renewable Energy Law

The ‘polluter pays’ principle is put on the

head:

We pay peatland agriculture for causing

massive climate damage

… and frustrate in this way sensible solutions

Peatland drainage causes even greater problems: subsidence!

… the “devil’s cycle” of peatland utilisation…

Bavaria: 3 m loss since 1836 UK: 4 m loss since 1870

Drainage subsidence (loss of height): 1 -2 cm annually

former land surface

Nether-lands …Nether-lands: bogged down: 1000 yr of peatland drainage,

now half the country deep under sea level…

Nether-lands …Nether-lands: bogged down: 1000 yr of peatland drainage,

now half the country deep under sea level…

In tropics

subsidence 5 times faster!

In NE-Germany, ten thousands of hectares have already been flooded as they could not be drained anymore economically

Germany

Many tropical peatlands are coastal and will - with continuous drainage and >2000 mm of rainfall - become undrainable …

The ‘ wave’ in oil palm plantations showing subsidence

Sabah

Oil palm plantation on coastal peatland will – in the near future - lead to the loss of substantial tracts of land

Aljosja Hooijer Sumatra

Whereas the sea level rises, we bog the peatlands down….

• Cultivation of biomass on wet and rewetted peatlands

bog: peat moss

fen: common reed, reed canary grass, sedges, alder, ...

• Utilisation of biomass for industry and energy

CINDERELLA Paludiculture

General aim of CINDERELLA

• to extend the scientific base for a sustainable use of wetlands and to make alternative uses accessible to farmers and land authorities. – give an overview on productive species, provenances and breeds;

– quantify GHG fluxes, C sequestration and nutrient retention as a basis for the assessment of ecosystem services;

– assess economic characteristics regarding ecosystem services;

– promote the exchange of scientific and technical knowledge;

– stimulate the cooperation among partners (countries and regions, private and public stakeholders);

– optimize synergies between regional climate change mitigation and adaptation;

– contribute to the necessary transformation of drainage-based peatland agriculture by best practice and stimulating acceptance.

Black Alder (Alnus glutinosa)

productivity: 3 – 10 t DM/ha*a

emissions: 0 t CO2eq/ha*a

Using peat as a

fuel

• finite fossil resource

• destruction of natural mires

• release of Carbon

from a long-term store

• net emissions of CO2

• is unattractive under

the Kyoto Protocol

Alternatives for energy from peat

106 t CO2 per TJ

Using biomass from wet

peatlands as a fuel

• renewable resource

• restoration of peatlands

• fixation of Carbon

into a long-term store

• emissions reductions of CO2

• is attractive under the Kyoto

Protocol and eg. VCS

- 130 t CO2 per TJ
